Falling film mode transition in an array of horizontal tubes : effect of two dimensional and three dimensional fins

Ma, Zhixian; Chen, Jingdong; Zhang, Jili (HEFAT, 2017)

Problem of falling film heat transfer is widely associated with many processes, such as shell side condensation and falling film evaporation in shell and tube heat exchangers. Efficient design of such heat exchangers can’t ...
Single-phase heat transfer and pressure drop performance in a horizontal internal helically-finned tube

Wang, Yonghui; Zhang, Jili; Ma, Zhixian (HEFAT, 2017)

Enhanced tubes with internally helical fins have been extensively used in the large heat exchangers. This paper experimentally determined the single-phase friction factor and heat transfer coefficients in an internal ...
